Also, here's a couple pretty good ones you left out:

"I am thus far a Quaker, that I would gladly agree with all the world to lay aside the use of arms, and settle matters by negotiation; but unless the whole will, the matter ends, and I take up my musket and thank heaven he has put it in my power." - Thomas Paine, July 1775.

"This difference is ascribed to our superiority in taking aim when we fire; every soldier in our army having been intimate with his gun from his infancy." - Thomas Jefferson, June 8, 1778.

"As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprize, and independance to the mind. Games played with the ball and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be the constant companion of your walks." - Thomas Jefferson, August 19, 1785.

"[O]ne loves to possess arms tho’ they hope never to have occasion for them." - Thomas Jefferson, June 19, 1796.
